Cosmology with voids

Benjamin C. Bromley, Margaret J. Geller

Voids are dominant features of the cosmic web. We revisit the cosmological information content of voids and connect void properties with the parameters of the background universe.…

The splashback radius and the radial velocity profile of galaxy clusters in IllustrisTNG

Michele Pizzardo, Margaret J. Geller, Scott J. Kenyon +1

We use 1697 clusters of galaxies from the Illustris TNG300-1 simulation (mass M and redshift range ) to explore the physics of the c…

Galaxy cluster mass accretion rates from IllustrisTNG

Michele Pizzardo, Margaret J. Geller, Scott J. Kenyon +2

We use simulated cluster member galaxies from Illustris TNG300-1 to develop a technique for measuring the galaxy cluster mass accretion rate (MAR) that can be applied directly to o…

An IllustrisTNG View of the Caustic Technique for Galaxy Cluster Mass Estimation

Michele Pizzardo, Margaret J. Geller, Scott J. Kenyon +2

The TNG300-1 run of the IllustrisTNG simulations includes 1697 clusters of galaxies with M covering the redshift range . We build mock spectros…

IllustrisTNG Snapshots for 10 Gyr of Dynamical Evolution of Brightest Cluster Galaxies and Their Host Clusters

Jubee Sohn, Margaret J. Geller, Mark Vogelsberger +1

We explore the redshift evolution of the dynamical properties of massive clusters and their brightest cluster galaxies (BCGs) at based on the IllustrisTNG-300 simulation. W…
